's eciication, reference being had thereinto t e accompanying drawing.

y inventionI relates to conveyer systems adapted to be used in high buildings, whereby avsingle elevator shaft may have its present capacity substantially doubled.. To ac complish this I preferably employ two elevater-carsI independently operated in the saine shaft one ruiming between a series of lower stories or landings and the other bein connection. with an intermediate conveyor preterably 1n the form of a moving stairway running between the intermediate stories or i landings forming the adjacent terminals of the two ears.

My invention consists in the arran Uements and organizations of parts hereinaiter described and then pointed out in the appended claims.

in `the accompanying drawing which exemplies an apparatus embodying my present invention, Figure 1 is a View inelevation opt'- 'a portion of an elevator shaft in which two elevator-cars are independently operated in connection with an intermediate inclined conveyer.; and Fig. 2 is a lan view of the elevator shaft andcar associated with a. pair Aot oppositely `movin inclined conveyors.

erring to the awin the numeral 3 indicates the elevator shaft in which the elevator-cars 4 and 5 are operated, and 6 and 7 indicatetwo intermediate floors or landings ot the buildin as the ninth and tenth or the nineteenth an twentieth respectively, 'and the ear d having its upper terminal at floor 6 and the can 5 havin its lower terminal at the succeeding or a jacent door 7.. The overhead work 8 oi' the car i` is just below the Vdooiz'ir and that oit the car 5 shown at 9 in drawing, may be located at any suitable point aboye floor 7. The cars are inde pendently operated and cont-rolled, and car flruns between the main or entrance floor (not `sho i to: amy intermediate' door as 6,

while th car 5 runs between the neat 1' her intermediate door 7i and` t door not shown). A,

Nmerals l0 and 11 indicate traveling conveyers, preferably in the' form of moving .,stairways, adapted to transfer passengers bef tween the floors 6 and 7, lObcing an ascend ing conveyer Vto transfer passengers trom floor 6 to tloor 7, and ll a descending con veyei to convey passengers from floor 7 to floor 6, these conveyers being driven from any suitable source of power and with their entrances and exits located adjacent the doors of the elevators.

Assuming that the cars in the shaft are 4so operated that the upper elevator com pletes its descent at the saine time the lower elevator com letes its ascent, when car 4 reaches the oor 6 it discharges the passengers which it took on, in its upward trip j from Vthe main floor-of the building, and tween a series of upper stories or landings, Y

upon the ascending conveyer l0 and are transported to floor 7 where they may enter car 5 after it has discharged its passengers. Those of' the passengers'iirom car 5, which discharges passengers on its down trip at floor 7, who may desire to get oli' at floors below floor 6 are conveyed from floor 7 to floor 6 by the descending conveyor 11 where they enter car 4 which is waiting for them., Each car then proceeds to complete its round trip, car 4 descending tothe main floor and stopping at an floor to take on or let oft' passengers,.fan car 5 likewise stoppin at the diierent tioorsfon its trip to and om the top` floor.

llt is. understood that while but one shaft having two elevator-cars operating `therein j is shown, in the actual employment of my invention banks each having a plurality ot shafts may be used, in each of which shafts two or more independently controlled cars may be operated. lt is of course also un derstood that while l have shown two cars inl each shaft with the inclined conveyers, three oi' more cars may be used in each-shaft if desired in connection with an inclined conveyor between each pair of intermediate terminals; thus in a building of sayforty ioors, the low-rise car 4 may run up to the nineteenth floor and the high-risc car from the twentieth ioor `to the top with the inclined conveyor service between the nine- 'teenth and twentieth Afloors, or the low-rise car may run to the ninth floor, the next car Vfrom the tenth to the nineteenth floor, the

next. from the twentieth to theftwenty-nnth between the ninth and tenth, nineteenth and twentieth, and twenty-ninth and thirtieth floors or landings. The division of the entire distance between the lowest and highest floors or landings may be made into as many .sections or zones as desired.

In order that there may be 'as little delay as possible at the transferring Hoors it is desirable to have the cars so operated that they reach these floors approximately at the same time, thereby reducing the time for the transfer of the passengers to a minimum, and for this purpose any suitable system of signal bells may be employed so that car 4 would leave the main floor at or about the time car 5 left the top floor and they would arrive at their destination at practically the same time. In actual use, however, as has already been stated, with banks containing a plurality of shafts in each of which are .operated two cars as just described, the delay of transferring the passengers would be materially reduced as there would always be. at the transferring floors at least two cars ready to convey them up or down as the case might be.

lVliere a plurality of shafts in each bank are employed it is apparent that man v different combinations of the cars may be operated. ln the saine shaft the two cars may be local-cars, or either one may be an expresscar and the other a local-car. or both may be express cars. And likewise of the cars running between the main and the nineteenth f floors and the twentieth' and the top floors;

in either case any proportion of them may be express-(ars as may be found desirable.

By employing the present system the space necessary for the shafts or wells is reduced one-half. and at the same time the elevator service is practically doubled as each car passes ,only the fioors that it serves and no car passes any zo'ne or\section not served by it, there being no idle runs. In systems heretofore devised some of the cars must run idle through certain partsof their flight, as an express car starting from the street level runs idle to the lloor where it begins to run local, but with my invention these idle runs are obviated and .each car operates only in its own zone.

The means for operating` the cars may of course be of any suitable character, as may all the ancillary parts of the entire apparatus.

Having described my invention I claim;

l. A conveyer system comprising two cars operating between different sets of terminals 1n the same shaft, and an inclined conveyer runningl between intermediate terminals.

2. A conveyer system comprisin two cars operating between different sets o terminals in the same shaft and different landings in the shaft intermediate the terminals, and an inclined conveyer running between adjacent landings.

3. In a conveyer system, two cars one above the other and passing different sets of terminals in the same shaft, and an inclined conveyer to transfer passengers between the cars.

4. In a conveyer system, a shaft, a plurality of independent cars one above the other and passino' different sets of terminals in said shaft, and a pair of oppositely moving inclined conveyers running between adjacent terminals.

5. In a conveyer system, two cars one above the other and operating in the same shaft from different terminals, the upper car having its lower terminal one floor above the upper terminal of thelower car, and an inclined conveyer to transfer passengers between the said lower and upper terminals.

6. yIn a conveyer system, two independent cars one above the other and operating in the same shaft from vdifferent terminals at each'end of the shaft. the upper car having its lower terminal one floor above the upper terminal of the lower car, and a' pair of oppositely moving inclined conveyers for transferring passengers between the said lower and upper terminals.

T. A conveyer system comprising an elevator-shaft divided into zones, each zone having upper and lower terminals, the lower terminal of each higher zone being above the upper terminal of the precedingr zone, a car operating in each zone, and an inclined conveyer connecting the adjacent terminals.

8. In aconveyer system, a shaft, a plurality of independent cars starting from different terminals and movable both upward and downward in said shaft, each car passing a separate series of landings, and an inclined conveyer connecting adjacent landings of different series.

' 9. In a conveyer system, a high-rise and a low-rise car operating between upper and lower sets of vterminals in the same shaft, andan inclined conveyer connecting adjacent terminals of the two sets.

10, In a conveyer system, two cars operating between upper and lower sets of terminals in the same shaft, and a pair of oppositely moving inclined conveyers connecting adjacent terminals of the sets.

1l. In a conveyer system, two cars operating in both directions between upper and lower sets of terminals in the same shaft, and an inclined conveyer connecting adja cent terminals of the sets.

In testimony whereof I aiiix my signature in presence of two witnesses. I
